If a doctor prescribes 200 mg of a medication available in 100 mg tablets, how many tablets should be given?

To determine the correct number of tablets needed when a doctor prescribes 200 mg of a medication available in 100 mg tablets, you must first understand how to break down the prescribed dose in relation to the available tablet strength.

In this scenario, the prescribed amount is 200 mg, and each tablet contains 100 mg. To find out how many tablets you need, you divide the total prescribed dose by the strength of one tablet:

200 mg (prescribed) ÷ 100 mg (per tablet) = 2 tablets.

This calculation shows that two 100 mg tablets are required to meet the total prescribed dose of 200 mg. Thus, the correct response to the question is indeed that two tablets should be given, effectively fulfilling the dosage requirement outlined by the doctor.
